Title: Improvements in motor driven road sweepers
IPC: E01H1/08
Filed: 1933-12-21
Abstract: 424,089. Road scavengering. ETABLISSEMENTS LAFFLY, 82, Rue du Vieux Pont de Sevres, Billancourt, Seine, France. Dec. 21, 1933, No. 35974. Convention date, Aug. 30. [Class 107] Relates to road-sweeping and collecting machines of the kind in which the choke-tube 7 of a suction device is mounted behind the delivery end of a rotary brush 3 which is inclined with regard to the longitudinal axis of the machine. According to the invention, the sweepings from the choke-tube are delivered, by a pipe 10, tangentially into a centrifugal separator 11 which is so connected to a fan 15 that the sweepings do not pass through the fan. In the construction shown, the tan is driven by the motor of the vehicle through mechanism comprising a countershaft 16, a trapezoidal belt 17, and a clutch ; alternatively, it may be driven by an independent motor. A pipe 14 from the fan is connected to a suction chimney 13 centrally disposed within the separator. The sweepings collect at the conical base of the separator from which they are discharged by opening a rocking gate 11<1>. The outlet pipe 18 of the fan opens at 19 at the level of and behind the sweeping brush, whereby any stray sweepings which pass through the fan are directed on to the brush. Separate hand controls may be provided for raising the choke-tube and brush, or both may be operated simultaneously by a single control lever.

Abstract: 1469179 Castors ACOUSA SAXON SA 15 Aug 1974 [1 Sept 1973] 36009/74 Heading A4U [Also in Division F2] A castor for hospital beds comprises a roller 24 mounted in a fork 13 rotatably attached to a fixing pin 1 by a combined axial and radial roller bearing 10, a spring-loaded spindle 5 extending axially through the pin 1 and being operable by a linkage member 3 to interengage toothed discs 15, 16 to prevent swivelling of the fork 13, and to engage a brake shoe 22 with the periphery of the roller 24. The spindle 5 is hexagonal in crosssection to prevent its turning. A part 11 of the roller bearing 10 is secured to the fork 13 by screws 12 which also serve to guide rectilinear movement of a brake member 14 on which the brake shoe 22 is hinged for adjustment by a screw 23, the brake member 14 being retained by a spring 17 passing upwardly through the spindle 5 to an anchorage on a bush 6. A spring-loaded bolt 18 is engageable in indexing holes 21 in the disc 16. In a second embodiment, Fig. 2 (not shown), the spring 17 is replaced by a headed screw (26) engaging in the bottom of the spindle 5, a spring (25) being interposed between the head of the screw and the disc 15. In a third embodiment Figs. 3 and 4 (not shown), the disc 16 has two diametrically opposed peripherical recesses (31) which in the uppermost position of the disc are engeable by a radial projection (32) on the fork 13 to prevent swivelling of the fork and to retain the roller 24 in a particular orientation relative to the bed. Moving the spindle 15 to an intermediate position permits swivelling of the fork and movement of the roller. The brake member 14 is pivoted to the fork and is moveable downwardly against a spring (36) disposed between the brake member 14 and the fork. The brake shoe 22 is replaced by a headed screw (37) adjustably engaged in the bottom of the brake member 14.

The screw comprises a sheet metal member 6 bent into helical form at 6<a> and rotatably mounted in a hole in the arm 4 by a split resilient locking ring 8. The upper portion of the member 6 is riveted to a knurled knob 7. The fixed bracket 5 is formed centrally with a slot 5<a> which registers with the end of the part 6<a> when the arm 4 is turned to the retaining position so that the screw may be engaged with the slot by turning the knob 7.

Title: New s-heterocyclic compounds and their use as mycobacteriostats
Inventor: HUGHES SHEILA ANN
IPC: C07D285/15
Filed: 1960-10-24
Abstract: The invention comprises compounds of formula: <FORM:0943273/C2/1> where X is -NR-CH2-S-, -NRCH2NR- or -NR-, R being an aliphatic- or aromatic-oxyphenyl or halogenphenyl group, which may be made by treating a compound RNH2 with H2S and HCHO.  For dithiazines preferably 1 mol. of the aniline is treated with 2 mols of H2S and excess HCHO and for thiadiazines preferably 2 mols of aniline are treated with 1 mol of H2S and excess HCHO. In both reactions thiazetidines are produced.  Mixtures may be separated by fractional crystallization. The excess of HCHO may be 1 to 4 mols more than the stoichiometric amount.  Reactions are preferably effected in a solvent e.g. ethanol, at -10 to 15, especially -5 to 5 DEG C. Representative of specified values of R are methyl, ethyl, n- and iso-propyl, butyl, octyl, methoxy-, dimethoxy, octyloxy, cyclohexyloxy, phenoxy- and chloro-, bromo- and iodo-phenyl groups. The substituent may be in the o-, m- or p-positions to the phenyl nucleus which may contain further substituents such as alkyl or halogen groups.  The compounds are used as myco-bacteriostatic agents, see Division A5. Examples are given of the preparation of 5, 6-dihydro-5-(p-ethoxy-phenyl)-5-(p-chlorophenyl)-1, 3-dithia-5-azines, 3-(p-ethoxy- and -chloro-phenyl)-1-thia-3-azetidines and 3, 5-di(p-ethoxy-and -chloro-phenyl)-tetrahydro-1-thia3, 5-diazines.  In the Provisional Specification R is an organo-oxyphenyl or halogenophenyl group.ALSO:Mycobacteriostatic compositions comprise compounds of the formula <FORM:0943273/A5-A6/1> wherein X is -NR-CH2-S-, -NR-CH2-NR-or -NR- and R is an aliphatic- or aromatic-oxy-phenyl or a halogenophenyl group, and an inert filler.  The composition may be a suspension, an emulsion or a solid, preferably containing from 1 to 25% of the active ingredient.  The suspension may be stabilized by a surface-active compound, such as a soap, a sodium salt of a long-chain alkylated aromatic sulphonic acid or an ethylene oxide condensation product.  The compound may be dissolved in an organic liquid, preferably insoluble in water, such as toluene, cyclohexane, petroleum ether, chloroform, chlorobenzene, castor oil, sperm oil, cottonseed oil, rape oil or mineral oil, which can then be emulsified in water, preferably stabilized by a surface-active compound.  They may be in the form of lotion, paste, cream or ointment.  Solid compositions can be made using a finely divided powder such as talc as the inert diluent.  Examples (2) and (4) illustrate the mycobacteriostatic activity of 3,5 - di(p - ethoxy- and chlorophenyl) - tetrahydro - 1 - thia - 3,5 - diazine.  In the Provisional Specification R is an organo-oxyphenol or halogenophenyl group.

Abstract: 1,154,518. Measuring speed electrically. AMETEK Inc. Aug. 11, 1967 [Aug. 26, 1966], No.37061/67. Heading G1N. A rotating drum has on each of a number of spokes 12 Fig. 1 permanent magnet 14 which as it passes a reed switch 16 mounted on a fixed member, changes over the switch contacts. This closes a charging circuit for a capacitor 34, which subsequently discharges when the magnet has gone and switch 16 is restored to normal, the voltage developed across capacitor 34 being indicative of the time taken for the magnet to pass it and therefore universely related to the speed of the drum. At a selected low speed, predetermined by adjustment of resistor 22 in the charging circuit, this voltage is sufficient to fire neon tube 38, followed by SCR 46, and a relay 44 is energized to effect an alarm or control action.
